Dpi, ppi, dip, dp, px, sp, dpippi Basic Concepts 1. dpi (dots per inch): The number of dots per inch; ppi (Pixel per inch): The number of dots per inch. Designed for the monitor, dpi = ppi. 2. dip (device independent pixels) devices are independent pixels. Different devices have different display effects, which are related to device hardware and do not depend

Turn to the user's answer:1. DPI is the dot per inch, how many dots, PPI is Pixel per inch, pixels per inch, for the design of the display, Dpi=ppi.The PPI calculation method is the sum of the length and width of each square, divided by the diagonal length (in inches). Principle can draw a rectangle of the Pythagorean theorem to calculate a calculation.2. PPI indicates the point density of the display devic

Conceptual interpretation Noun Explain Px(Pixel pixels) Different devices show the same effect. The "Same" here means that the number of pixels does not change, such as specifying a UI length of 100px, regardless of the resolution of the UI length is 100px. This is why the UI is magnified and distorted on small-resolution devices, and is scaled down at large resolutions. Screen Size(Screen size) Generally speaking, the size of a mobile pho

Concept:DPI (dots per inch): points per inch, initially used to measure the density of dots per inch on the print, and how many points the printer plays in an inch. The smaller the DPI value, the less fine.PPI (Pixels per inch): The number of pixels per inch, when the concept of DPI is used on an electronic screen, it should be called the PPI.For developers, DPI

Length Unit In typography, "point" is an absolute unit that is equal to 1/72 inches and can be measured by a ruler, in physical inches. But the meaning of PT in CSS is not so, for example, we specify a font is 9PT, we would think that according to the CSS specification, it is equal to: 9 * 1/72 = 1/8 inch This is a misunderstanding, because our display is divided into pixels, a single pixel can only have one color (for simplicity, the pixel anti-aliasing technique is not discussed here), to be

1. px (pixels) pixels-is a pixel, which is the actual pixel unit on the screen. Dip or dp (device independent pixels) device independent pixels, related to the device screen. Sp (scaled pixels-best for text size): similar to dp, it mainly deals with the font size. Dpi (dot per inch): screen pixel density, how many pixels per inch There is a member with the same name in the android api. The method is as follows: 2.

Http://doc.qt.io/qt-5/highdpi.htmlQt Support Ability to provide pixmaps or artwork for high Resolution:see Drawing High resolution Versions of Pixmaps and Images. Qt 5.4 introduces experimental support for scaling by-device pixel ratio similar to OS X to the platform plugins for Wi Ndows and Unix (XCB). This was controlled by the environment variable QT_DEVICE_PIXEL_RATIO . It can be set to a numerical value to being used as scale factor or "auto" which causes the scale factor to be

With technology in power generation, many PCs or tablets are now configured with high-resolution display screens, and many friends will set up a larger DPI (especially on a small size screen) to make the fonts on the screen look clearer when Windows is installed. Although some software interfaces may have blurred problems after setting a larger dpi, some settings allow them to be displayed in their original

As a pad product, the screen is 7-inch and the resolution is 1024*600. The Code provided by the chip manufacturer is running, but the visual effect is very poor. At first glance, we can see that the wallpaper has been severely stretched, and the color block and sawtooth of the image are obvious, at first it was suspected that the screen driver was not properly tuned and the driver was specially optimized for the LCD driver, but the problem was not significantly improved. Finally, the system calc

Release a software for batch processing of image printing resolutions (DPI) Purpose: When you insert an image into a word, you may find that the inserted image is larger or smaller. Very difficult. The reason is that when word is processing an image, the DPI of the image is 96 by default, so for an image with 72dpi, it will become larger when it is inserted into word; for a picture with 300dpi, it w

The screen has a fixed physical long width attribute and resolutionLike a computer, like a phone screen.For example, the phone screen size is 1.5 inches x2 inches, the screen resolution is 240x320,Then you can calculate the number of pixels per inch (dpi) in the horizontal direction: 240/1.5=160, can also calculate the vertical direction per inch1PX refers to a pixel on the screen, the principle of screen imaging is through the screen dense pixel poin

What is DPI:The DPI English full name is "dots per inch", literally "pixels per inch", which means the pixels per inch. (1-inch =2.54cm), refers to the inside of the mouse decoding device can identify the length of pixels per inch. (The smallest unit on the screen is a pixel). This is a static unit, so this parameter is typically applied to printers and scanners.To give a simple example: Join us using 400dpi Microsoft IE3, then the mouse on the mouse

The default font size for the WINDOWS7 operating system is 96 pixels, so we face a very big problem: the default 96-pixel font size of the Win7 operating system makes it hard to read text or do text-related operations with a high split screen. Long-time operations can cause damage to our eyesight. To solve the problem mentioned above, we can adjust the text size on the screen by adjusting the DPI setting of the Win7 . Operation Steps 1, "Desktop spa

To tell the truth, the resolution of our system has not been low, for many users, such visual effects have been regarded as enjoyment, but with the rapid development of science and technology in recent years, we win8 computer screen resolution has been correspondingly improved, Now the average computer screen resolution has reached the 1920x1080, of course, the higher resolution is there. However, in many WIN8 computers, the Windows system's default DPI
